Reply To: Exporting a large number of data sets into TXT from varFDTD

[Matt Wilson]

Hi, sorry to be a pain with this haha. So I have rewritten my script as per your suggestion. This is what I now have:

Ex = real(getdata("E_field", "Ex"));

Ey = real(getdata("E_field", "Ey"));

 

x = getdata("E_field", "x");

y = getdata("E_field", "y");

z = getdata("E_field", "z");

f = getdata("E_field", "f");

 

x_max = length(x);

y_max = length(y);

z_max = length(z);

 

lambda = (c/f) * 10^9;

 

for (m=1:5){

fileName = num2str(lambda(m)) + "nm.txt";

E = sqrt(Ex(1:x_max, 1:y_max, 1:z_max, 1:m)^2 + Ey(1:x_max, 1:y_max, 1:z_max, 1:m)^2);

write(fileName, num2str(E(1:x_max, 1:y_max)), "overwrite");

}

It prints the E field data into a text file but it only seems to be doing it for the first data set (i.e. not iterating through the different wavelength values). Can you suggest where I could fix this?
